Test Pin of BS 1363-1 Figure

This Test Pin is a dedicated safety tool designed to verify protection against access to hazardous live parts in plugs, socket-outlets, and adapters for the UK market. Compliant with BS 1363-1:2018 Figure 1, it features a 1mm diameter steel pin (20mm long) for accessing narrow gaps in electrical connections, plus an insulating handle for user safety. The precision-machined spherical radius (SR) on the pin tip ensures it mimics real-world contact scenarios, delivering reliable results for checking if UK-standard electrical components block unauthorized access to dangerous parts.

Standards:

Specifications:
Test Pin Diameter:  Φ1mm (±0.02mm tolerance, ensures compatibility with BS 1363-1 gap requirements)
Test Pin Length:  20mm (±0.05mm tolerance; critical for reaching potential hazardous parts)|
Spherical Radius (SR):  Precision-machined SR on pin tip (matches BS 1363-1:2018 Figure 1 dimensional specs)
Material Composition – Pin: High-grade steel (corrosion-resistant, maintains diameter accuracy); – Handle: Insulating material (prevents electrical contact during testing)
Key Tolerances:  Linear dimensions: ±0.05mm (aligns with BS 1363-1:2018 Clause 9 precision requirements)

Test Procedures:
1. Inspect the test pin for bent steel, cracked insulation, or worn tips; confirm diameter/length meet specs.
2. Power off the plug/socket/adapter under test and place it on a stable, flat surface.
3. Identify potential access points (e.g., gaps in plug prongs, socket openings) per BS 1363-1.
4. Hold the insulating handle, align the pin tip with the target gap, and gently insert until resistance is felt.
5. Check if the pin can contact hazardous live parts (via visual inspection or electrical testing).
6. Record results to verify compliance with BS 1363-1:2018 Figure 1.

Applications:
1. Safety testing of UK-standard household plugs (e.g., 3-pin mains plugs) per BS 1363-1:2018.
2. Compliance checks for socket-outlets (e.g., wall sockets, extension lead sockets) intended for the UK market.
3. Quality control for adapter manufacturers (e.g., travel adapters converting to BS 1363 plugs) during production.
4. Third-party certification testing (e.g., UKCA, CE) for electrical components seeking UK market entry.
5. Post-production audits of plug/socket batches to ensure consistent adherence to BS 1363-1 safety norms.
